(Reuters) - Russia plans to resume nuclear submarine patrols in the southern seas after a hiatus of more than 20 years following the break-up of the Soviet Union, Itar-Tass news agency reported on Saturday, in another example of efforts to revive Moscow’s military.

The plan to send Borei-class submarines, designed to carry 16 long-range nuclear missiles, to the southern hemisphere follows President Vladimir Putin’s decision in March to deploy a naval unit in the Mediterranean Sea on a permanent basis starting this year.

“The revival of nuclear submarine patrols will allow us to fulfill the tasks of strategic deterrence not only across the North Pole but also the South Pole,” state-run Itar-Tass cited an unnamed official in the military General Staff as saying.

The official said the patrols would be phased in over several years. The Yuri Dolgoruky, the first of eight Borei-class submarines that Russia hopes to launch by 2020, entered service this year.
